NEWARK, OHIO, A. CORPORATION OF OHIO GGOK $TOVE Application filedJanuary 21, 1929. Serial No. 334,074.

The invention has general reference to cook stoves and more particularlyto the mounting of the door or doors of the oven section. It has for itsgeneral aim the provision of a simple and advantageous construction forhingedly mounting an oven door in a manner such as to conceal the hingeconnections in all positions of the door.

More specifically it is an object of the invention to provide a stovedoor construction in which the hinge members are positioned andconcealed within the body of the door frame.

7 A further object of the invention is to provide an improved,simplified form of means for counterbalancing the weight of the ovendoor.

Still another object resides in the provision of exceedingly simple,readily disconnectible means for hingedly connecting a door on a stove,which is concealed in all positions of the door and is positionedsubstantially in the plane of the supporting wall of the stove.

Another object of the invention is to provide a device of this characterwhich is simple and sturdy in construction, is capable of beingmanufactured cheaply, may be easily assembled and disassembled and inwhich v the mounting means is adequately protected E against accidentalinjury or damage.

Other objects and advantages will become apparent in the followingdescription and from Figure 1 is a front elevation of a preferred 3 5embodiment of the invention, the stove being shown fragmentarily. Fig. 2is a vertical central section thereof taken approximately on the line2-2 of Fig. i 1, the center panel being omitted. Fig. 3 is an inner facevlevv of the back section of the door frame.

While the invention is susceptible of various modifications andalternative construc tions, I have shown in the drawing and will hereindescribe in detail the preferred embodiment, but it is to be understoodthat I do not thereby intend to limit the invention to the specific formdisclosed, but intend to cover all modifications and alternativeconstructions falling within the spirit and scope of the invention asexpressed in the appended claims.

Generally the invention is capable of application to any preferred typeof cook stove and is illustrated in connection with an oven door. Thisdoor, generally stated, comprises a pair of readily separableinterfitting sections constituting the frame thereof. Said sections arespaced apart so that the frame is hollow and the members, by which thedoor is pivotally supported or hinged on the stove, are located andconcealed in the hollow space of the frame. Furthermore, substantiallythe entire construction may be manufactured from sheet metal, and thearrangement of parts is such that the assembled structure is extremelyrigid and sturdy.

More particularly describing the invention, 10 designates one of theside walls of the stove which has therein an opening into the interiordefined by a frame 11. T he frame generally is of a well recognizedconstruction and, if desired, may embody an outward ly facing recess,shown at 12, around the inner margin thereof which snugly receives thedoor in the closed position thereof. The door, in its generalarrangement of parts, has the usual central panel 13 carried andsupported by a door frame, indicated at 14. A handle 15 facilitatesopening and closing the door.

Referring particularly to the door frame construction, said framecomprises a. pair of interfitting sections, namely, a back or supportingsection 16 and a front or shell section 17. These sections, when inassembled relationship, form a rigid, sturdy frame within the frame andmay be of which the panel may be mounted in any suitable manner.

In Figs. 2 and 3, the back section 16 is shown as comprising a flat,centrally apertured member having inner and outer peripheral flanges 18and 19 extending in one direction therefrom to provide a channel shapedstructure. The outer edges of the inner flanges 18 may be bent inwardlyof the central aperture, as at 20, to form an abutment for use inpositioning and mounting the panel 13 in place.

The front section or shell 17 has the same general contour as the backsection and is also provided with inner and outer periph eral flanges 21and 22. The shell, however, is somewhat wider than the back section 16so that the flanges 21 and 22 thereon fit over flanges 18 and 19 on theback section. As may be seen in Fig. 2, the outer peripheral flange 19on the back section is somewhat shorter than the inner flange 18, sothat the surface contour of the shell 17 may slope correspondingly toenhance the ornamental appearance of the door.

In securing the sections together one side edge, in this instance thelower, of the outer flange 22 on the shell is bent inwardly, as at 23(see Fig. 6), and is arranged to be received in a slight indentation orrecess formed along the corresponding edge of the back section. Thisprovides a positive interengagement therebetween extending entirelyalong one side of the two sections. The handle 15 is mounted on theopposite, or upper, side of any suitable type such as a hand piece 24supported by a pair of posts 25.

The shell is struck inwardly at appropriate points to provide flat seats26 for the handle posts 25, and screws 27, extending through both theback and the front sections 16 and 1.7 axially into the legs 25, securethe two sections and the handle in rigid assembly. Preferably spacingmembers, which may be in the form of sleeves 28 suitably secured to theback section 16 for engagement with the rear surfaces of the indentedportions 26, are provided to insure a definite spaced relationship ofthe front and back sections. inner flange 18 on the back section mayalso abut the shell, serving to further insure such relationship. Thusthe frame of the door may be assembled by merely effecting theinterengagement of the complementary sides of the two sections and thensecuring the handle in place.

The simplified form of hinge construction utilized in mounting the doorupon the stove comprises a pair of elongated members 29 and 35 havingthereon integrally formed complementary means which, when connected,formthe hinge. The elongated member 29 is welded or otherwise securedwithin the channel of the back The c section 16 on the side" thereofopposite the handle and has near either end thereof a pair of spaced,alined curls or loops 30.

The other elongated member 35 is, for the purpose of providing greaterrigidity to the assembly, secured along the side of the stove frame 11intermediate said frame and the upper portion of the adjacent stovewall, which, in this instance, is the skirt 36 (Fig. 6). The member 35carries near either end thereof a single curl or loop 31 supported atthe end of a forwardly projecting arm 31 (Fig. 6) which extends througha suitable notch in the flanged upper edge of the frame 11. Thearrangement of parts is such that each of the loops 31 entersbetweeu andis alined axially with a pair of spaced loops 30 on the member 29 whenthe door is properly positioned on the stove.

egistering apertures 32, 33 in the hack section and shell (Figs. 1, 3and 6) respective ly, which form in effect a downwardly opening notch inthe hollow frame permit extension of the curls 31 and arms 31 into theinterior of the door frame, such apertures extending away from the edgeof the door for a suflicient distance to permit swinging movement of thedoor. Pins 34, extending through the alined curls 30, 31 complete thehinge members and are preferably removable to facilitate dismounting ofthe door. To expose the hinges for the purpose of dismounting the door.the outer section 17 of the door is removed by unscrewing the bandle 24.The fact that the hinge members 29 are connected to the inner section 16of the door materially simplifies the initial assembly of the stove,since the parts of the hinge may be connected together while they are inexposed readily accessible positions, after which the outer section 17of the door may be secured in place. If desired, the member 29 may bereinforced by bending one side thereof at substantially right angles, asshown at 37. It will be seen, therefore, that the hinge construction isexceedingly simple and. since all the permanent units between the partsmay be easily accomplished by spot welding, an exceptionally sturdy andrigid structure is attained.

The preferred arrangement and location of the parts of the hinge membersis such that the pivotal axis of the hinges lies immediately within theouter edge of the door frame. Consequently. only a small portion of theframe swings inwardly of the stove as the door is opened, and the stoveframe adjacent this edge of the door is offset inwardly or recessed, asat 38 (Fig. 6), to provide clearance for this portion of the door frame.For the sake of clearness, the edge of the door is herein shown ashaving considerable clearance. Furthermore, the arms 31 are arranged toposition the pivotal axis substantially in the plane of the wall of thestove.

, door,

Hence, a simple hinge of this character may be employed without impairing the close abutment of the door frame with the stove frame.

In connection with a door construction of this character it becomespossible to provide a simplified means for counterbalancing the weightof the stove door. While a single counterbalancing organization wouldprob ably operate effectively, better balance is obtained by using oneon either side of the stove door. However, since the organizations inthe present embodiment are substantially similar, only one will bedescribed in detail. Referring to Figs. 2, 3, 4, and particularly 7, thecounterbalancing means comprises an arm 38 preferably formed as anintegral part of a plate 39 secured within one of the side channels ofthe back section 16 of the frame.

The arm 38, in the mounted position of the extends through anappropriately formed elongated slot 40 in the stove frame, and acontractile spring 41 extending between the arm 38 and a bracket 4:2 ona stationary part of the stove, exerts a downward pull upon the arm tohold the door in closed position. Preferably the arm 38 curvesdownvardly to permit the spring force to be exerted substantially in theplane of the stove wall. A stop finger 43 formed on the arm 38 forengagement with the stove frame limits the extent of outward swingingmovement of the door. The slots 40 in the stove frame are preferably ofsuch size that there is no engagement between the stove frame and thearm 38 in any of the relative positions of the arm to the frame, thuseliminating any possilulity of wear on the frame.

It will be apparent that a door construction has been provided in whichthe operating parts are substantially concealed from view in anyposition of the door. Moreover, the operating parts are readilyaccessible for inspection, repair, or replacement of the parts, and theentire construction is exceedingly simple and sturdy.

I claim as my invention:
